# Opencrow Stego Toolbox

> Use the OpenCROW steganography stack for hidden-data triage and extraction. Use when an agent needs `steghide`, `zsteg`, or when a full install tracks manual StegSolve or OpenStego setup.

## About

# OpenCROW Stego Toolbox

## Runtime preflight

Probe required commands with `command -v` and Python modules with `importlib.util.find_spec` before use. Prefer a PATH-resolved OpenCROW MCP helper or the `ctf`/`sage` environment when available, then the managed helper or system Python. If a capability is missing, stop that path safely and report the exact missing command or module.

Use this skill for image or audio artifacts that may hide data in metadata, bit planes, or container structures. It covers `steghide` for embedded payload extraction and `zsteg` for PNG/BMP stego triage.

## Quick Start

Start the MCP server from the installed CLI:

```bash
opencrow-stego-mcp
```

Verify the mapped stack:

```bash
python3 scripts/verify_toolkit.py
```

## Workflow

1. Start with `zsteg` when the target is a PNG or BMP and you suspect LSB or plane-based data hiding.
2. Start with `steghide` when the file type matches its embedding model and a passphrase may be involved.
3. Combine this toolbox with `opencrow-forensics-toolbox` when metadata or carved files may be involved too.
4. If a full profile was installed, use the manual StegSolve or OpenStego steps from the installer summary for GUI-assisted analysis.
5. Prefer the MCP server operations first: `toolbox_info`, `toolbox_verify`, `toolbox_capabilities`, `stego_inspect`, and `stego_extract`.

## Resources

- `scripts/verify_toolkit.py`: confirm that the mapped stego tools are installed.
